     Three young pioneers were playing while they saw a young    
tree bending to one side with some of it's leaves falling.    
They felt sadness and decided to save it. They put            
up a hard stick close by and tie the tree to                  
it to make it straightly. Then they make a fence              
around it to prevent people and animals of                    
coming near. They also put up a board there, on that          
they wrote:"Cherish young tree." After that, the             
three often came to watering the tree. Gradually,             
the young tree grew straight and strong. Their teacher learned
this and praised them, "Well do. Children."                  		1.________
